24 to 48 VAC/VDC Digital Input Modules This figure is a simplified schematic for models 3502E, 3503E, and 3505E, which are 24 to 48 VAC/VDC, 32-point TMR Digital Input Modules with a self-test feature. YPQ202A YT204001-KBThe self-test feature continuously verifies the ability of a Tricon controller to detect the transition of a normally energized circuit to theYPQ202A YT204001-KB Off state.Specifications This table lists the specifications for model 3502E, which is a TMR Digital Input Module with a nominal input voltage of 48 VAC/VDC and a self-test feature.Color code Dark red Number of input points 32, commoned in groups of 8 Input frequency range DC or 47-63 Hz Recommended input range 35–95 VAC/VDC Maximum voltage 95 VAC/VDC Switching level: Off to On 27 VAC/VDC typical, 32 VAC/VDC worst-case Switching level: On to Off 14 VAC/VDC typical, 11 VAC/VDC worst-case Typical hysteresis 7 VAC/VDC Nominal turn-on 6 mA to 9 mA Input impedance > 2.9 kΩ nominal Input delay: Off to On <8 ms Input delay: On to Off <15 ms Point ***lation, opto-***lated 1000 VAC minimum, 1500 VDC minimum Status indicator: On or Off state 1 per point Status indicator: Module status Pass, Fault, Active <10 watts Nominal fieldYPQ202A YT204001-KB power load 1.0 watts per On point, 3.2 watts @ maximum field voltage Leakage current to chassis @ 60 Hz 0.5 mA maximum per On point Input diagnostic fault coverage1: Maximum input toggle rate 1. The maximum input toggleYPQ202A YT204001-KB rate enables proper operation of I/O diagnostics and detection of all normally detectable faults. The minimum toggle rate provides fault coverage of normally undetectable faults within 10% of the calculated mean-time-between-faults (MTBF) for the module.
